摘要
揭示了积分移相法原理测量无功功率的相角误差问题,提出一种简便的解决方法,并对最后实用模型的性能,诸如采样频率影响,频率响应特性等进行了分析。
This paper introduces the phase error caused by the phase shift method in initial stages using integral for reactive power measurement and puts forward a solution. The characteristic of a practically available model are discussed, such as the effect of sample frequency, frequency response and etc.
